  • Patent number: 9450654
    Abstract: A system and a method are provided. The method includes deploying a plurality of antennas of an access point or a base station as a distributed antenna system. The method further includes configuring the distributed antenna system for multi-user wireless transmissions by applying medium access techniques and power-balanced pre-coding at the access point or the base station. The method also includes providing device localization for devices communicating with the distributed antenna system by applying time-difference-of-arrival techniques to antenna pairs from among the plurality of antennas at the access point or the base station.

  • Patent number: 9378085
    Abstract: A method for estimating a block error rate and a communication device are applied to the field of communications technologies. The method for estimating a block error rate includes: decoding N received coded code blocks to obtain multiple posterior probabilities APPs, where N is a natural number greater than 1; obtaining, according to the multiple posterior probabilities APPs and a preset policy, a result indicating that the decoding of each coded code block is correct or incorrect, where the preset policy includes: when a sum of absolute values of the multiple APPs is greater than or equal to a preset threshold, the decoding is correct; and obtaining a decoding block error rate according to a result indicating whether the decoding of the N coded code blocks is correct. In this way, the estimation of a decoding block error rate is implemented.

  • Publication number: 20150315069
    Abstract: A glass of the present invention includes a first layer having a porous structure of nanoscale pores which are etched by an etchant that is a substitute for hydrofluoric acid (HF) or fluoride such that HF or fluoride is not used as the etchant, and a second layer which is not etched by the etchant. The glass is effectively applied to various applications requiring high light transmission such as a protective filter for a display device, a solar cell, a mobile communication device, glass of a building structure, and an optical element lens.

  • Publication number: 20150234033
    Abstract: A method and an apparatus are provided for determining the location of a mobile device using multiple wireless access points, each wireless access point comprising multiple antennas. The apparatus and method are particularly suited to location of a mobile device in an indoor environment, such as a building. The method includes receiving a communication signal from the mobile device at each of multiple antennas of said multiple wireless access points; for each wireless access point, determining angle-of-arrival information of the received communication signal at the wireless access point, based on a difference in phase of the received signal between different antennas; collecting, from each of the multiple wireless access points, the determined angle-of-arrival information for the received communication signal from the mobile device; and estimating the location of the mobile device from the collected angle-of-arrival information.

  • Patent number: 9112076
    Abstract: A glass substrate manufacturing method of the present invention comprises forming a multi-porous structure layer which comprises nano-size pores at a surface of a glass substrate by etching the surface of the glass substrate with hydrofluoric (HF) acid or an etchant substituting for fluoride. Unlike related art methods, the glass substrate forms no additional coating layer, uses no harmful chemical material, and is given anti-reflection, anti-fogging, and super-hydrophilic characteristics through a simple process at a relatively low temperature. The glass substrate is effectively applied to various applications requiring high light transmission such as a protective filter for a display device, a solar cell, a mobile communication device, glass of a building structure, and an optical element lens.
